A layer with a mass/unit area 1,0 kg/m2and a thickness 1,0 mm is considered to be a non-substantial component Note 1 to entry: Two or more non-substantial layers that are adjacent to each other (i.e. with no substantial component(s) i

39、n between the layers) are regarded as one non-substantial component when they collectively comply with the requirements for a layer being a non-substantial component.

42、e, etc. 4 Principle The reaction to fire classification (Euro classes) shall be determined in accordance with EN 13501-1, respecting the test conditions of the ETICS laid down in this standard. In order to evaluate the reaction to fire all kits of the design ETIC system as well as the individual com

43、ponents shall be considered. Test results may be also valid for the assessment of the reaction to fire of further design ETICS. Rules are given below. NOTE 1 A European reference fire scenario has not been laid down for facades. In some Member States, the classification of ETICS according to EN 1350

44、11 might not be sufficient for the use on facades. An additional assessment of ETICS according to national provisions (e.g. on the basis of large scale tests) might be necessary to comply with Member State regulations, until the existing European classification system has been completed. NOTE 2 In s

45、ome Member States the requirements might exist to demonstrate the behaviour of products with respect to continuous glowing combustion in the case of fire. Additional national assessments e.g. on the basis of national procedures to demonstrate this behaviour might be required until a European harmoni

46、zed procedure will be available. 5 Instructions for mounting and fixing, field of application 5.1 General This clause gives instructions for mounting and fixing for reaction to fire testing of a kit and its single components. This clause includes the field of application of the test results of the k

47、its as well as of its single components. EN 16724:2015 (E) DIN EN 16724:2017-05 7 Base coats shall be grouped according to the binder type into inorganic (cement-calcium hydroxide, alkali silicate, etc.) and organic (silicon resin, synthetic resin, etc.) coats. Finishing coats shall be grouped in th

48、e same way. For each group of base coats and finishing coats the product with the highest organic content shall be tested in combination with the adhesive having the highest organic content. If there are only differences in the organic content but no difference in the organic component itself, the p

49、roduct with the highest organic content shall be tested. The test results are valid also for adhesives, base coats and finishing coats with equal or lower organic content. If adhesives, base coats or finishing coats include flame retardants, those components with the lowest amount of flame retardant shall be tested additionally. The key coat and the decorative coat may be neglected if the layer thickness of each coat is less than 200 m and the orga
